BACKGROUND

1. Technical Field

The present invention relates to a road traffic system.

2. Related Art

Since emergence of motor vehicles, big and small cities in the world have been successively trapped into “traffic blocking”, big and small cities in China are no exception, and with rapid development of the cities, how to crack the traffic blocking has become a worldwide super problem. Especially level-crossing traffic controlled with traffic lights is always criticized by people. Road design and planning mainly focuses on right of way of the motor vehicles, when pedestrians cross the road at an intersection point, the green light time is too short, plus right-turn and turnback vehicle streams, the right granted by the green light when the pedestrians cross the road is severely infringed, the existing planning fails to effectively ensure absolute safety and right of the pedestrians, resulting in that the traffic rules lost prestige, leading to a vicious circle, the pedestrians are forced to reversely infringe upon the right of way of the motor vehicles, which usually bets life safety, in combination with that a group of people huddle together to cross the road at any time, to strive for the road with the motor vehicles at the risk of the red light, dangerous signs of the traffic appear incessantly, more seriously, Chinese road crossing is everywhere, the speed of the vehicle stream is usually harassed, the traffic cannot be accelerated, let alone full-speed operation, the crossroad with low passing efficiency is greatly reduced accordingly, and more annoyingly, all sides directly turn left into the vehicle streams, to cause intersection conflict at countless cross-shaped intersection points, which becomes a bottleneck blocking point, and urban traffic in China can only stumble.

Although, in recent years, three-dimensional traffic and collective rail transportization have been effective in directing traffic, renovation throughout the city is costly and by no means easy, with the existing financial resources, only key transformation is feasible, and an overwhelming majority is the road traffic controlled with traffic lights. It is difficult for the existing traffic control technologies of traffic lights and road planning to handle various steering demands of motor vehicles at level crossings, especially left-turn vehicle streams, and when left-turn vehicles constantly gather at each cross point, traffic jam naturally becomes a common urban phenomenon. Hence, innovatively transforming traffic in planar crossed congested roads and optimizing the traffic of traffic lights by economic means make men and vehicles equally share the right of way, and vehicle streams in all directions switch the course harmoniously, which increases the operation speed, eliminates congested blackspots at level crossings, takes advantage of new planning to point out ideal roads, where bus stops go out and come in without obstructing other vehicle streams, as stations, and clears hotbeds produced by traffic bottlenecks, and such low-cost high-effectiveness traffic planning and transformation is especially important and urgent.

SUMMARY

An objective of the present invention is to, in order to overcome the deficiencies of the prior art, provide convenient anti-bottleneck mode traffic of vertical and horizontal interactive man-vehicle public transportation at level crossings which is deployed precisely and makes pedestrians, motor vehicles and buses all feel easy and smooth.

In order to solve the foregoing problem, the present invention adopts the following technical solution:

According to the crossed road traffic system described as above, characterized by: further including a transitional road section connected with the main roads, the transitional road section being provided thereon with an isolation belt, and two sides of the isolation belt, from inside to outside, being sequentially provided with two transitional through lanes and a bus and right-turn combined lane.

According to the crossed road traffic system described as above, characterized in that: the road front section is provided thereon with one front section right-turn lane, one front section turnback lane and two front section through lanes, and three front section through lanes are disposed on the road front section in a direction of driving away from the crossroad.

According to the crossed road traffic system described as above, characterized in that: the outermost one in the three front section through lanes is a bus stop lane.

According to the crossed road traffic system described as above, characterized in that: the road rear section is provided thereon with two rear section right-turn lanes, two rear section through lanes, one rear section turnback lane and two rear section through lanes.

According to the crossed road traffic system described as above, characterized in that: one end of the road rear section near the crossroad is provided with a landmark that allows vehicles on an adjacent lane to go straightly through the crossroad.

The present invention has the following beneficial effects: 1. due to addition of one lane, two ends of the main road are just divided into two, to become a pair of turnback vehicle lanes in opposite directions, there are a total of four pairs of, that is, eight, turnback vehicle passage zones in vertical and horizontal sides, each pair of turnback vehicle passage special zones just shield pedestrians to be sandwiched in the middle sidewalk to cross the road, who safely cross the road completely without other interference, the time during which the pedestrians cross the road is equal to that of the vehicle streams in the same direction, there is no reduced interference, in other words, men and vehicles share the right of way equally, the green time during which the pedestrians cross the road is greatly increased, Chinese road crossing is no longer in existence, because there is no need to run risks to overcome obstacles.

2. The level crossing has no direct left-turn, there is no intersection conflict, and the crossroads are no longer main traffic blocking points.

3. Rearward shift of the sidewalk and planning of road rear sections make the level crossing have room for increase, right-turn vehicles can all have temporary stay places, the pedestrians pass at first, and then the vehicles pass according to law after the light turns green. In this way, there is no need to strive to be the first with the pedestrians on the sidewalk.

4. The turnback lane, like steering 360 degrees, plus 90 degrees turned right in advance, a left-turn effect that 360 degrees minus 90 degrees is 270 degrees is formed, increased turnback lanes and lanes easy for right-turn provide vehicles with rich steering combination selections, to make the vehicles more flexible and quickly adjust the line easily even if running in the wrong direction.

5. Level crossing traffic makes full use of the land, does not waste the land at all, and keeps a balance of eight-in-eight-out vehicle streams, a vehicle overstock phenomenon no longer appears, and the traffic is smoother.

6. A bus stop port section is disposed in front of the rear section turnback lane, while the front of the bus stop is provided with a bus/right-turn combined lane, in a road environment with a way before and no end collision after, the situation where lots of buses frequently go out of and come into stations to affect surrounding vehicle streams no longer occurs, and traffic circulation will become smoother.

7. There is increase but no decrease in selection of forward course of any point on the main road, situations such as one into two, one into three and one into four, two into three, three into four, and four into six are very common, while eight into twelve is common at crossroads, such an anti-bottleneck mode from fewer to more greatly ensures significant reduction of traffic bottlenecks and makes the traffic smoother.
